Abstract

The invention relates to a silk screen mould used for liquid wallpaper, in particular to a technology for producing a liquid wallpaper silk screen mould. The technology for producing a liquid wallpaper silk screen mould comprises the following process flow: firstly, designing a pattern; making the film of the pattern; interlinking a drawn vector diagram with a film machine by EX9000 software to make a film picture; developing in a prepared developing solution; carrying out photographic fixing in fixing solution after imaging; cleaning with water after several minutes; drying for standby; tightly arraigning a silk screen onto an aluminium alloy frame by a screen arranging machine; coating aqueous photosensitive glue on a silk screen plate; exposing pictures; flushing the silk screen plate; flushing the exposed silk screen by using a high pressure gun, wherein the silk screen plate is cleaned for the first time, pressure is slowly adjusted from low to high; finally, drying the cleaned silk screen in an oven or in the sun; putting the dried silk screen on a detection rack to ensure that the quality of the silk screen does not have problems. The can be reused, and has the advantages of long service, easiness of clean and high precision.

Description

The production technology of liquid wallpaper silk screen mould

Technical field

The present invention relates to the screen template that a kind of liquid wallpaper is used, relate in particular to a kind of production technology of liquid wallpaper silk screen mould.

Background technology

The defective that present existing screen stencil exists is: access times are few repeatedly, each masterplate repeatedly service time short, be difficult for producing in batches, to clean repeatedly and be difficult for wash clean with alcohol during cleaning, also have some meticulous line images to be difficult to show its effect.

Summary of the invention

At the defective of prior art, the object of the present invention is to provide a kind of service time long, easy cleaning, the production technology of the liquid wallpaper silk screen mould that precision is high.

To achieve these goals, the technical solution adopted in the present invention is: the production technology of liquid wallpaper silk screen mould, and its technological process is: the first step, the design design is preferably the suitable polar plot of size dimension earlier;

Second goes on foot, and makes the film sheet of this figure, will draw good polar plot, connect with EX9000 software and film chain and to produce film picture, in the developer solution for preparing, develop, put after the imaging to the fixing solution photographic fixing, take out after several minutes in the clear water the inside and clean raffinate, the back is dried stand-by naturally;

The 3rd step, the net machine stretches tight silk screen on the aluminum alloy frame with stretching tight, the tight work on screen frame of silk screen is called the net that stretches tight, comprise the tension of silk screen and fixing on frame, it is convenient that the quality of net of stretching tight can have influence on each of print quality, as the precision of position and fit, the definition of pattern edge, the uniformity of China ink layer and the degree of reticulate pattern;

The 4th the step, on the silk screen version brushing aqueous sensitizing glue, adopt method gluing from top to bottom, suggestion gluing speed 10-12CM/ minute, then dictyosome is put into thermostatic drying chamber, temperature 35-40 degree, relative humidity 60% (was as the criterion to parch) about 30 minutes drying times, drying box planted agent open cycle scavenger fan, temperature contrast can not be greater than or less than 2 degree up and down.

The 5th step, publish picture (be commonly called as and shine plate) of exposing, polar plot is placed on the on glass of exposure machine, the silk screen that scribbles photoresists is fixed on the exposure machine exposes, the exposure effect of different exposure machines is variant, time for exposure need be tried out the back and be determined, the reference exposure time: 30=60 second, when the coating method that adopts not simultaneously, adjust the time for exposure according to the thickness of latex.

The 6th step, flushing silk screen version, the silk screen that available giant flushing has exposed, hydraulic pressure is unsuitable too high, in order to avoid the photoresists above the silk screen are washed out, during first the flushing, can slowly regulate from low to high, will wash good silk screen at last and under the oven for drying or the sun, dry.

The 7th step, colour-separation drafting are placed on dried silk screen and check on the frame, scrutiny dictyosome face, as sand holes occur and can repair with the photoresists that prepare, make silk screen before stamp, guarantee not have quality problems.

The invention has the beneficial effects as follows: can use repeatedly, service time is long, easy cleaning, precision height.

The specific embodiment

Following embodiment is not as a limitation of the invention, and all any modifications of being done in the present invention's spirit and principle are equal to replacement and improvement etc., all belong within protection scope of the present invention.

The production technology of liquid wallpaper silk screen mould, design design earlier, make the film sheet of this figure then, good polar plot will be drawn, connect with EX9000 software and film chain and to produce film picture, in the developer solution for preparing, develop, put after the imaging to the fixing solution photographic fixing, take out after several minutes in the clear water the inside and clean raffinate, the back is dried stand-by naturally; The net machine stretches tight silk screen on the aluminum alloy frame with stretching tight, brushing aqueous sensitizing glue on the silk screen version, adopt method gluing from top to bottom, suggestion gluing speed 10-12CM/ minute, then dictyosome is put into thermostatic drying chamber, temperature 35-40 degree, relative humidity 60%, (be as the criterion) about 30 minutes drying times to parch, drying box planted agent open cycle scavenger fan, temperature contrast is not more than or spends less than 2 up and down, polar plot is placed on the on glass of exposure machine, the silk screen that scribbles photoresists is fixed on the exposure machine exposes, when the coating method that adopts not simultaneously, adjust the time for exposure according to the thickness of latex.Flushing silk screen version, the silk screen that available giant flushing has exposed, hydraulic pressure is unsuitable too high, in order to avoid the photoresists above the silk screen are washed out, when washing for the first time, can slowly regulate from low to high, to wash good silk screen at last dries under the oven for drying or the sun, dried silk screen is placed on the inspection frame, scrutiny dictyosome face, a complete set of technology is finished.
